100 Doors 2013 is the sequel of the one of the most popular puzzle games, 100 Doors. The game features 100 Doors with different puzzles to solve. It is available for both Android and iOS devices. If you are stuck, check out the walkthrough for floors 1-110 here. On January 13, an update increased the levels to 119. Below is the guide for floor/door 115.
Level 115 / Door 115 Answer: Enter the code “31193” on the keypad. How we solved it: The hint above the elevator is the tribonacci number. Solve for the missing X and Z numbers. The pattern for this Tribonacci equation is the sum of the three previous numbers. For instance:
- 1+1+1 = 3
- 1+1+3 = 5
- 1+3+5 = 9
- 3+5+9 = 17
- 5+9+17 = 31 = X
- 31+57+105 = 193 = Z
So, X=31 and Z=193. The code is “31193”
Congratulations! You completed the first door, level 111, of the new update! Continue to level 116.
